ports for Air-Brake Systems; and I do here- .by declare thefoll-owin to be va full,- clear,

. and exact description the invention, such 10 as will enable others skilled in theart to which it appertains tornake and use the same.

In air brake mechanism the angle cock has" I secured to one of its ends the flexible hose andcoupli-ng, an ditheother end is interiorly threaded to. receive the ex'teriorly threaded endof the train pipe. The pipe is weakened; to such a degree by the threads that should the angle cock be subjected tonndue or excessive strains, as .oftenhappens',fr the pipe" breaks at the place or-circular line adjacentto its connection with the angle cock. Such breakage renders the air brake inoperative, the angle cock hose and coupling often are lost,-and considerable e'xpenseforj repairs becomes n'ecessa Further, the Master Car Builder 'sta'n ards for the'appIication of air bra es to cars specifythe location of. the train pipe and angle .cockrlative tothe oou ler an the .ahgulandisposition' of the ang ecock to a vertical plane, ,and itfis'de- 'sirable that they shall be hgldl invtheir Proper positions. v-

The object ,of am invention: is ifiis uleprovision of means constituting" an'inu'proved connection or union of the angle cock and;

- pipe which shall transmit-anddistribute. the

- strains from; the angle cock-to the relatively strong part of thef plpe backlofthe threaded; end-portiom'and, secondly, the provision of ymeans for holding" the lan-g lejcock in its proper position on the c f r.andii elativqrto With these w,

' 1. The combination with afcar havingan element provided with an opening, of an angle cock and a train pipe, .a threaded clamp, and a threadedclamplng put; the clamp engaging the angle cock and the clamp ng nut surrounding the train pipe and engaging thethreads of the clamp; the

parts being so relatively disposed that the said element of the car is clamped between the clamp and the clamping nut When the nut is seated.

2. The combination with a car having an element provided with anopening, of anangle cock and train pipe, a threaded clamp formed in a plurality of pieces, and a threaded clamping nut; one end of, the clamp engaging the angle cock and the 'opposite threaded end engaged by the threaded clamping nut; the element provided-With an opening being clamped between the clamp and clamping nut;

. 3. The combination with a car having an' element with an opening, of an angle cock and train pipe, the said angle cock having a flange at the end adjacent the pipe; a

' threaded clamp formed in av plurality of pieces; and a threaded clamping nut; one end of the clamp engaging the flange-of the angle cock and the threaded end-being en gaged by the threaded clamping nut; the said element otthe car being clal'nped be tween the clamp and clampingnut.

4. The combination in an air brake angle cock support, of a car; an angle cock angularly shaped exteriorly at one end; a train pipe secured to the angle cock; a clamp havmg one-end i'n'engagement with the angular end of the angle cock and the other end .thr ded and-bearing against the train pipe;

a 't re'aded clamping nut on the pipe engaging the threaded end, of the clamp and means in connection with the car holding the angle cock and, pipe in fixed positlon relative thereto. i

5. The combination in an air brake, angle cock'support, of a car; an angle cock angularly'. Shaped exteriorly at one end; a train pipe secured to the an 'le cock; a clamp formed in a plurality of pieces ha ving one end in engagement with the angular end of the angle cock and the other end threaded and bearing against the train pipe; a threaded clamping nuton the pipe engaging the threaded end of .the clamp; and means in connection with the car holding'the angle cock and train pipe in fixed position relative thereto.

6. The combination with an angle cock at one end interiorly threaded and angularly shaped extcriorly, of-a clamp formed in a plurality of parts With one end en aging the angularly shaped exterior of the angle cock and the other end exteriorly threaded a threaded clamping nut on'the pipe. engaging the threaded end ofthc clamp; and an element in connect-ion with a car supporting the angle cock train pipe and clamping means'in a fixed position, real-tive to the car,

7. The combination with an angle cock interiorly threaded and. having an exterior flange, of a threaded tram plpe, a clamp formed in a plurality of parts,-one end having a flange engaging the flange of the angle cock and the opposite end threaded, a"

threaded clamping nut 011 the pipe engaging the threaded end of the clamp; and means -for supporting said angle cock pipe and clamping elements in fixed position relative to'thecar. g

8. The combination with an element in connection with a car, said element having a web, of an angle cock and train pipe, a threaded clamp, and a threaded clamping nut; the clamp engaging. the angle cock and web and the clamping nut screwed onthe clamp and alsoengaging the web.

9. The combination with an element in connection with a'car. said element having an opening, of an angle cock and train pipe, a threaded clamp formed in a'plurality of pieces, and a threaded "clampingnut; the,

clamp engaging the angle cock and element in connection with the car and the clamping nutscrewed on the clamp and alsbengaging the said element l0. Clamping means for uniting an angle cock and train pipe comprising aclamp .formed in a plurality of pieces the interior surface thereofat one end angular-1y shaped and the opposite end exteriorly threaded,

and a clamping nut interiorly threaded and angularly shaped exteriorly and adapted to engage the threaded end 0 the clamp.

11. Clamping means for uniting an angle cock and train pipe comprising a clamp access formed in a plurality of pieces the interior surface thereof at one end shaped to fit'the angle cock, the opposite end e'iteriorly threaded and with an intermediate exterior flange at right angles to the longitudinal axis of the clamp, and a clamping nut interiorly threaded and angularly shaped exteriorly'and adapted 'to engage thethreaded end of the clamp.

12. In a device of the character described, the combination of atrain pipe and angle cock, a support mounted on the car frame and having a bearing for: the pipe, and a pair of threaded members cooperating with said pipe and angle cock and adapted to be screwed one upon the other against opposite sides of said support to pipe and angle cock against surface thereof atone end shaped to fit the angle cock, the opposite end exteriorly tapered and threaded and with an intermediate exterior flange, and a clampingnut interior-1y tapered and threaded and adapted to engage the threaded end of the clamp.
